19 All that openeth the matrix is mine; and every firstling among thy cattle, whether ox or sheep, that is male.

20 But the firstling of an ass thou shalt redeem with a lamb: and if thou redeem him not, then shalt thou break his neck. All the firstborn of thy sons thou shalt redeem. And none shall appear before me empty.

Counter-apologetics

This is generally okay advice, but certainly shouldn't be a law.

Some parents don't deserve to be honored, such as child abusers.

In United States law

The 5th commandment is not a part of U.S. Law or (legal) custom. There is no law in the U.S. requiring a person to respect their parents. A minor may be considered to be under the jurisdiction of parents (providing the parents are not considered "bad" parents). However, once a person reaches the age of majority, this no longer applies and the child is afforded all of the right and protections toward the parents that they are afforded to any other person. Cursing ones father or mother is protected in the Bill of Rights under free speech protections.
